The aim of the study was to recognize attitudes towards product reliability in the furniture industry. The results are presented of the research conducted in 75 Polish and Slovenian furniture companies, focusing on the manner in which enterprises determine the length of the warranty period and which tools they implement to evaluate the reliability of the furniture construction. The data was collected through direct interviews and surveys. The high level of recognition of reliability and quality as key success factors for the next 5-20 years in the furniture industry was observed. A positive correlation was explored between the size of the enterprise and the existence and use, during the design process, of a database detailing structural failures. A coexistence of variables was found connected with the use of a failures database, an implemented, integrated CRM (Customer Relationship Management) system and the offering of an extended warranty period. The results of the study confirm the necessity and importance for furniture-manufacturing companies to consider reliability and warranty issues in their industrial practice.","PeriodicalId":50566,"journal":{"name":"Drewno","volume":"60 1","pages":"133-149"},"PeriodicalIF":0.8,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chemical and crystalline structure, physical and mechanical properties and the optical properties were investigated in OCC papers delignified using reinforced oxygen delignification methods. The relative degradation rates were determined at 4.02% for oxygen delignification reinforced with sodium percarbonate and 0.62% for oxygen delignification reinforced with hydrogen peroxide at a 2% alkali charge. The results showed that paper sheet properties following oxygen delignification reinforced with hydrogen peroxide were better than for those following oxygen delignification reinforced with sodium percarbonate and pure sodium percarbonate. It was determined that the whiteness value was higher following oxygen delignification reinforced with sodium percarbonate rather than any of the other reinforcing agents, while the highest ISO brightness value was found following oxygen delignification reinforced with hydrogen peroxide.","PeriodicalId":50566,"journal":{"name":"Drewno","volume":"60 1","pages":"47-64"},"PeriodicalIF":0.8,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper is to explore the perception of innovation within the furniture industry in Poland. Empirical research was conducted in two stages. In the first, based on the findings of analyses published by the Central Statistical Office, the innovation activity of furniture enterprises was evaluated in comparison with that of all Polish industry. The second stage comprised primary research, the aim of which was to collect opinions from furniture manufacturers on certain aspects of innovation activity. The analysis was conducted in 80 medium-sized and large furniture enterprises. The research tool was an interview questionnaire composed of 31 questions. From the primary research it was found that the greatest influence on an increase in demand for furniture was a price reduction of the product. The most significant factor influencing the decision on the part of entrepreneurs regarding the introduction of innovation was its economic justification. The main factor curbing innovation activity in furniture enterprises was a lack of funds.","PeriodicalId":50566,"journal":{"name":"Drewno","volume":"59 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
